Hi,
ath5k no longer works for me in 2.6.31.[1-2].
2.6.31 worked good enough even though in patched 2.6.30.3 the connection and association
is seemingly more stable.
All tests done in ad-hoc mode with 2 computers, the other end is a rt73usb which
is not quite trouble free either.
I have now confirmed that going back to 2.6.31 the wlan works at least most of the
time and completely stops working after applying this patch on top of 2.6.31

One more odd observation - since 2.6.31 "iwlist wlan0 scan" will list my own ad-hoc
network twice although there are really only 2 machines.
